Title: Adsorption type gas refining method
Inventor: MIZUNO MICHIKAZU
IPC: B01D53/02
Filed: 1982-08-25
Abstract: PURPOSE:To obtain gaseous hydrogen, which is a product, with high purity and a good recovery rate by recycling a part of waste gas into raw material gas in an adsorption type gaseous hydrogen system. CONSTITUTION:Raw material gas to be used contains 100Nm<3>/h gaseous hydrogen and 5Nm<3>/h impurities similarly to the prior art, and the recovery rate in the section of an adsorption tower is made similarly 60%. The same raw material, the same adsorbent and the similar operating pressure are used. The flow of recycling gas is adjusted to 5:1 ratio to waste gas by a recycling gas valve 12, and is incorporated into the raw material gas. The total recovery rate in this case is 90%, which is 30% higher than that in the prior art, thus indicating that the much larger amt. of the refined gaseous hydrogen is separated from the waste gas usable heretofor only for the fuel purpose alone.

Title: Device for turning workpiece support of vertical shaver
Inventor: UENO KENJI
IPC: B23F19/06
Filed: 1984-07-19
Abstract: PURPOSE:To easily set a final angle through quantization, by providing a drive system for a manually-rotated handle which is used to turn a workpiece support in the unit of a very small angle, relative to the body of a counter column secured on a bed. CONSTITUTION:When a manually-rotated handle 12 is rotated, the rotation is transmitted to a workpiece support 11 by a pinion 13, a gear 14 and hypoid gears 15, 16 while the speed of the rotation is reduced, so that the workpiece support is turned coaxially with the hypoid gear 16. The numbers of the teeth of the pinion 13, the gear 14 and the hypoid gears 15, 16 are designed to turn the workpiece support 11 by an angle of 0.01 deg. when the handle 12 is rotated by one round. The support 11 can thus be easily turned only by rotating the handle 12. An aimed inclination angle for the workpiece support 11 is divided by the unit angle of 0.01 deg. to rotate the handle 12 by the quotient to exactly adjust the support 11 to the aimed inclination angle without trial and error.

Title: Method for charging raw material in blast furnace
Inventor: MIYAGAWA SHOJI
IPC: C21B5/00
Filed: 1990-06-08
Abstract: PURPOSE:To secure gas flow at the center part in a blast furnace and to prevent increase of pressure drop at bulky zone by separating raw material coke with a sieve and alternately charging mixed material of large lump coke and powdery coke with ore and middle lump coke into the blast furnace. CONSTITUTION:The raw material coke is sieved to separate the medium lump coke. The obtd. large lump and powdery cokes are mixed in the ore and this mixed material and medium lump coke are alternately charged to the blast furnace 1. In the blast furnace 1, at the time of charging the mixed material layer 3 after charging the coke single layer 2, a part of the coke mixed in the mixed layer is re-separated and segregated at the time of flowing down, to form the segregate layer 4 at the furnace center and near the furnace wall. In this method, coaser the grain size of the coke mixed in the mixed layer is, more easily re-separated is the coke, and the amt. of segregation thereof in the furnace center becomes much more. On the other hand, as the large bulk coke has good permeability, the gas flow at the center in the blast furnace can be secured.

Title: Co-processor arithmetic unit
Inventor: KURISU YOFUMI
IPC: G06F15/78
Filed: 1987-06-15
Abstract: PURPOSE:To make the calculating speed of a co-processor arithmetic unit higher, by providing a zero-data detector and omitting the multiplying and adding calculation on matrix elements having the value of zero as much as possible from the beginning. CONSTITUTION:When matrix calculation AX is carried out, the elements of a matrix A are written in a memory device 2 in the unit of line from the outside. When the elements are written, the addresses of the leading elements of the lines, at which non-zero is detected, are stored in a starting address register 3 and the addresses of the tailing elements of the lines, at which non- zero is detected, are stored in an ending address register 4. The contents of the registers 3 and 4 are updated whenever a non-zero element is detected. When a co-processor 8 carries out matrix calculation, the processor 8 reads the contents of the registers 3 and 4 before starting the calculation of each line and executes sum of products calculation on the read lines only. Therefore, the speed of matrix calculation of this arithmetic unit can be improved.

Filed: 1979-11-14
Abstract: PURPOSE: To record and read out the signal without distortion, by digitizing the signal after discriminating the signal level, and adjusting the gain so that the level is a signal to the region indicating linear response of the device.  
     CONSTITUTION: The signal 1a is made to a signal 1b with an attenuator 1 suitably set for the gain and made to a signal 2a at an amplifier 2 and fed to a comparator 4. The comparator 4 makes the signal 4a to "1" when the signal 2a exceeds the signal Vr made of the reference voltage corresponding to the voltage to start the digital conversion, and it is input to the control circuit 10 and the conversion operation is started by giving the signal 10a to the A/D converter 3. The converter 3 digitizes the signal 2a to be a signal 3a and it is input to the level detection circuit 6. When the circuit 6 detects the signal 3a exceeds the linear response region, the signal 6a is made to "1" and fed to the gain adjuster 9 to change-over the set of the attenuator 1 to greater attenuation rate. Thus, the signal can be recorded and read out without distortion.

IPC: H02P5/68
Filed: 1989-06-14
Abstract: PURPOSE:To make a motor compact and to improve economization by using a constant voltage (constant torque) control circuit and a speed control circuit of a motor in common and by switching from one to the other control above with a simple transistor circuit. CONSTITUTION:If a control system switching signal L is applied to the base of a transistor Q7 in a constant voltage control circuit 3 through a resistance R9, a speed control circuit 2 will be operated as before. When a control system switching signal H is applied, transistors Q7, Q5 and Q6 are turned ON. As the base voltage of transistors Q2 and Q3 becomes almost equal to the supply voltage VCC, a current mirror circuit is turned OFF. The voltage VS at a power terminal 15 in an output stage of a motor drive circuit 1 becomes almost equal to the supply voltage and is led to a constant voltage control circuit. The speed control and the control voltage (constant torque) control can thereby be mutually switched, so that the constitution can be made compact and economical for the motor.
